Iterate through nested snapshot children in Firebase using Swift

Question

I\'m trying to loop through children in my Firebase Database to retrieve a nested key.

My database is structured like this:

\"Users\" : {
 \"Username\" :

The problem in your code is that snapshot refers to the Favorites node – instead of looking for LocationName there, you should look for it inside each of the Location child nodes. Therefore your loop should look something like this:

let databaseHandle = databaseRef.observe(.value, with: { snapshot in
    for child in snapshot.children {
        let childSnapshot = snapshot.childSnapshotForPath(child.key)
        if let dbLocation = childSnapshot.value["LocationName"] as? String {
            print(dbLocation)
        }
    }
})
